Database Specialists, Inc. In the output, its giving me error " Error in CREATE TABLE of EXPLAIN PLAN table:$plan_table ORA-00922: missing or invalid option parse error offset: 1050 EXPLAIN PLAN option disabled." Can Warm regards, Archana Pandey "No one can do the things, He thinks he can't do." Top For discussions on Oracle Database Tuning please visit the Oracle Database group. The execution plan is made available to you in the form of rows inserted into a special table called a plan table. More about the author

This information came from the "other" and other_tag columns of the plan table.

If you are using Oracle 8.1.5 or later, you can find two plan query scripts in $ORACLE_HOME/rdbms/admin. There are many different ways to format the data retrieved from the plan table. Oracle is able to perform simple filtering operations while performing a full table scan. The rows column along the left side of the execution plan contains a count of how many rows of data Oracle processed at each step during the execution of the statement.

You might look at the object_owner column, for example, if objects in multiple schemas have the same name and you are not sure which one is being referenced in the execution Fix is: create a plan_table in the explain schema using the standard script: $ORACLE_HOME/rdbms/admin/utlxplan.sql Regards, Yoann. The 14 calls used a total of 0.59 CPU seconds and 0.99 seconds of elapsed time.

The output of the latter script is more confusing, so only use it when parallel query or DML come into play.

In this situation, each server process will create a trace file containing trace information about the operations performed by that process only.

  • Forgot your password?
  • For each customer record, the invoices_view view will be assembled as a filter and the relevant contents of the view will be examined to determine whether the customer should be part
  • In its simplest form, you run TKPROF specifying the name of a SQL trace file and an output filename.

  • From the counts of parse, execute, and fetch calls, you can see if applications are making appropriate use of Oracle's APIs.

The actual statement is never executed by EXPLAIN PLAN. Here Oracle evaluates each row from the input one at a time and either adds the row to the output or discards it as appropriate. As we will see later, TKPROF merges valuable information from the trace file into the execution plan display, making this just about the most valuable way to display an execution plan. Re: TKPROF prob in generating EXPLAIN PLAN 445907 Feb 10, 2008 5:01 PM (in response to chuckers) I'm on and have that error-so it is not bug to 10.1 version:

Next, the set of contacts and the set of customers will be joined using the merge join algorithm. my review here Whenever you run UTLXPLAN.SQL it only creates PLAN_TABLE in that particular schema where as your statement shows$plan_table which is confusing. If you have multiple execution plans in the plan table, then you should delete selectively by statement_id. For example, if an application opens a cursor and fetches 1000 rows from the cursor one row at a time, there will be over 1000 separate entries in the trace file.

In other words, there were 33,633 hits in the buffer cache and no misses. If you use the EXPLAIN parameter without the TABLE parameter, TKPROF uses the table PROF$PLAN_TABLE in the schema of the user specified by the EXPLAIN parameter. As with the EXPLAIN PLAN statement and the autotrace facility in SQL*Plus, you will need to have access to a plan table. click site The distribution column gives information about how the multiple Oracle processes involved in a parallel query or parallel DML operation interact with each other.

It's only the explain option that requires reconnecting to the db. If you specify sys=n, TKPROF will exclude from the report SQL statements initiated by Oracle as the SYS user. Because of the hierarchy, you need to use a CONNECT BY clause in your query from the plan table.

For example, a query against the dept table might have an execution plan that consists of an index lookup on the deptno index, followed by a table access by ROWID.

Note that tracing a database session that is using multi-threaded server (MTS) is a bit complicated because each database request from the application could get picked up by a different server Looking at the CPU and I/O statistics, you can see which statements consume the most system resources. SQL> SET AUTOTRACE ON SQL> SELECT * 2 FROM emp e, dept d 3 WHERE e.deptno = d.deptno 4 AND e.ename = 'SMITH'; EMPNO ENAME JOB MGR HIREDATE SAL COMM ---------- When SQL trace is enabled for a database session, the Oracle server process handling that session writes detailed information about all database calls and operations to a trace file.

Special database events may be set in order to cause Oracle to write even more specific information--such as the values of bind variables--into the trace file. If the TRACEONLY option prevented the query running, you would expect it to return instantly, like an EXPLAIN PLAN. Did I read anything into the execution plan? The SQL statement being examined can be thought of as the root of the tree.

We can also see that, although no disk I/Os were necessary, it took quite a bit of processing to complete this query. Is there something else that could be causing it?

This would manifest itself in lots of time spent on recursive SQL statements initiated by the SYS user.

Is the application submitting large numbers of simple SQL statements instead of bulking them into PL/SQL blocks or perhaps using array binds? Consider the following query and execution plan: SELECT a.customer_name, COUNT (DISTINCT b.invoice_id) "Open Invoices", COUNT (c.invoice_id) "Open Invoice Items" FROM customers a, invoices b, invoice_items c WHERE b.invoice_status = 'OPEN' AND The SQL statements can be listed in a TKPROF report in the order of how much resource they used, if desired.

SQL trace is a facility that you enable or disable for individual database sessions or for the entire instance as a whole. Want to Advertise Here? A sample TKPROF report for the invoice item query we've been using so far is as follows: TKPROF: Release - Production on Wed Aug 9 19:06:36 2000 (c) Copyright 1999 Any comprehensive database management tool will offer this capability, but there are several free tools available for download on the internet that have this feature as well.

The values that would be bound are not relevant since the statement is not actually executed. Also note that the filter operation can take on a few different forms. EXPLAIN PLAN The EXPLAIN PLAN method doesn't require the query to be run, greatly reducing the time it takes to get an execution plan for long-running queries compared to AUTOTRACE.

It's all there! I did run the utlxplan.sql, and that created the PLAN_TABLE in my schema.
